Module produces EDK gEfiPrintProtocolGuid for backward compatibility support. | |
EDK II retires old EDK Print Protocol and this module produces | |
gEfiPrintProtocolGuid based on PrintLib: | |
1) If it links against BasePrintLib in MdePkg, it produces gEfiPrintProtocolGuid | |
without any prerequisites. | |
2) If it links against DxePrintLibPrint2Protocol in MdeModulePkg, it produces | |
gEfiPrintProtocolGuid on top of gEfiPrint2ProtocolGuid. | |
